Application filed September 12, 192i. Serial No. 500,235.

able a so-ealled lantern globe of standard form, usually employed in portable lanterns, to be utilized as the globe o'fa street lamp, and toiprovide improved means for movably supporting the globe in such man ner that it may be conveniently displaced -h'om, and returned to, its operative pos1 tion, to permit access to theburner, without removal from the supporting means, and may be conveniently removed from, and engaged with, the supporting means.

The invention is embodied in the improvements hereinafterdescribed and claimed.

Of the accompanying drawings forming a part of this specification,

Figure 1 is a side elevation of: a lamp embodying the invention Figure 2 is a section on line 22 of Figure 1, and a side view of the portions below said line.

Figure 3 is a section on line 33 of Figure 2.

Figure 4 is a section on line 4-4 of Figure 2.

Figure 5 is a fragmentary section on line 55 of Figure 4.

The same reference characters indicate the same parts in all of the figures.

In the drawings, 12 represents a supporting member or base, which as here shown, is a socket adapted to be secured to the upper end of a fixed lamp post. Secured to the base 12 is an air-conductinghollow casing 13, through which air is adapted to pass, as indicated by arrows in Figure 2. The casing 13 is provided at its upper end with a horizontal annular seat 14, for the lower end of a 'so'called lantern globe 15 of glass, the

globe being open from end to end, and of the standard formused in portable lanterns. The (2218111 13 is also )lOVlClBCl at its upper end with means for-laterally confirr mg the globe on the seat 14, and permitting u g iward displacement of the globe, said .means being preferably embodied in an "upwardly projecting annular flange 16, loosely entering the lower end oi the globe. 17 represents a burner, projecting above thec'asing and surrounded the globe, the burner here shown being of the Welsbach type, and supplied with or with a mixture of gas 1 and air by a pipe 18.

19, 1.9 represent spaced apart standards, to, and rising from the base 12. 20 rep ents a rigid horizontal ring, secured to the upper ends of the standards, and pro vided with an inwardly projecting annular flange 21. 22 represents a tapering annular coi'u'ining member, preferably formed as an inverted cone ifrustum, and made of sheet metal by a suitable spinning 'or stamping operation. The larger end of the confining member is provided with an annular bead 23, and is formed to rest loosely on the flange 21. The smaller, lower end of the confining member 22 is formed to project below the ring 20 and somewhat closely surround the upper end portion of the globe 15, and is provided with clamping means separably engaging the globe, said means being best shown by Figure 3, and embodied in a length of resilient wire, bent to form a looped neck '24, curved arms 25, 25, arranged to embrace the upper end portion of the globe below an outwardly projecting bead 26 thereon, andxend portions 27, 27,

projecting through a slot in the member 22.

The'resilience of the'wire causes the arms 25' to normally embrace or clamp the globe, and the arrangement issuch that when pressure is exerted on the end portions 27, to move tne same tin-opposite directions, as indicated by the arrows in Figure 3,"the arms 25 are forced outward, so that the lantern bead 26 may pass freely between them. The saidclamping means permits the globe and" the confining member 22 to be moved upward in unison in a rectilinear direction, as indicated by dotted lines in Figure 2, so that the lower end of the globe may be raised abovethe burner to permit access to and emoval'of the latter. 'Y

28 represents an air-conducting hollow dome, supported bythe' fixed. ring 20, and having a cylindrical enlarged lower portion of greater internal diameter than the conlower end by a ring 32, to which the hinge member 29 is attached, said ring being separably engaged with the sheet metal body of the dome by means such as confining.

screws 33, engaged with cars 3% on the 32, the inner ends 01" said screws projecting over an outwardly projecting bead 35, formed on the lower end of the body portion of the dome.

.Fixed to the upper end of the dome 28 is a sleeve or extension 36, of perforated sheet metal, which permits the escape of gases and of air passing upwardly through the casing 13, the globe 15, the confining member 22, and the dome 28, as indicated by arrows in Figure 2. I

The extension 36is provided with a sheet metal cover 37, having a depending flange 38 surrounding the extension and permitting the escape of air and gases.

It will now be seen that the globe 15, and the confining member 22, may be vertically displaced to permit'access to the burner 17,

without removing the globe and the confinmg member from the supporting means and without displacing the dome 28, and that the globe when vertically displaced, may be readily separated from the confining member and removed from the supporting means. It will also be seen that the confining member 22 may be readily removed when the dome is swung upwardly. The supporting base 12, the standards 19, and the fixed ring 20, constitute a frame in common use as an element of a so-called. boulevard lamp, and adapted to support a casing located below. the burner, and a relatively large boulevard globe 40, of the form shown by dotted lines in Figures 1 and 2.

The lower end of a globe 4L0 of this form may bear on the lower portion of the casing, and its upper end may be supported Loosely by the ring flange 21, as in an ordinary boulevard lantern.

It will be seen that by providing a casing said seat and flange constituting a lower.

ea set and permit upward movement of the latter,

while the confining member 22 constitutes an upper adapter, separably engaged with the upper end of the lantern globe, and removably seated on, and laterally confined by the fixed ring 20.

The hollow casing 13 is'prei erably detachably connected with the base 12 so that it may be released by giving it a partial rotation, and raised from the base to permit access to mechanism located below the burner, such as a mechanism for turning on and shutting 0rd the The casing enclosing said. mechanism has heretofore been immovably to the base and provided with a side opening and with a door or cover closing said opening, the door being within the usual. boulevard globe lO so that the globe has to be independently raised to permit access to the door. ll am enabled by detachably connecting the casing 13 with the base 12, to raise the casing, the globe and the confining member or adapter 2 in unison.

l provide the interlocking members next described r eetachably connectin the ing 13 Wltll the case 12. L1

The bas 12 is provided with 'tWo oppositely pr gecting arms i1 (Figure 4:) supporting an upstinring ring 42 having ears lf; pyogectmg my rdly ti-om its upper edge, as suown oy higure 5, said ring and ears The lower end of the casing 13 is provlded with outwardly project, 1g annular flange 14: having notches 44 arranged to coincide with the ears 43 as shown by full lines in Figure 4. said. flange and its notches.

constituting the other interlocking member. The casing is also provided with an external inclined annular flange L5 arranged to rest loosely on the ring 42 so that the ring supports the flange 45 and the casing; To secure the casing to the base 12, the casing is held in position to cause the flange notches id to coincide with the ears 4L3, and is moved downward until the flange dais below the ears. The casing is then partly rotated to move the notches 44; out of alinement with Figure 42-, the flange l i being thus interlocked or engaged with the ears to prevent upward movement of the casing 13. A movement of the casing to return the notches 4% to the full line position enables the casing to be raised from the base. A perforated plate or screen 47 (Figure 5) may be attached to the ring 42 to exclude insects from and admit air to the casing 13, said screen-being formed to surround the upper portion of the base 12. The inclined flange 45 is extended outward and its lower edge surrounds an outwardly projecting annular flange d8 on the 'uting one of said interlocking meinring as. The flange a5 is rigidly secured to the casing 13 and serves as a root to exclude water and snow from the interlocking members so that said members cannot be rendered inoperative ice and rust.
